It's the first service I've seen like this that's based on providing localized content to users.

People are getting used to things always on at the home. They're entertaining it out to mobile environments wherever that may be, in the car or at the supermarket. You start noticing that you use some similar tools at home and work, and you want more access back and fourth — but there are barriers.

The specs are fine [on the iBook] but the price is still out of reach of the average consumer user.
